' 'Specifleation of LettersPatent.

To-alZ- who-m it may oancem =Be it known thatrl, ARTHUR EH. GmsoN, a subject of. the Crown of. GreahBritain, and resident of Fasten, inztherconnty of Northamptonend-State of Pennsylvania, have. invented new and useful lmprovements in Mining Machines, of which the 'fol-lmwing is a specification.

My invention relates to. improvements. in mining machines and is directed to machines which-are well adapted ton use in operating upon coal.

"My invention relates more-particularly toment of the several parts whereby the coal puncher truck may be moved baek andfforth alongthetrack; by power and in which'the puncher itself may be swung :horizontally into different positions by power, and held yieldingly in such positions, and lnWhiCh the puncheritself may beswung'vertically into kli iierent positions an d h-el d yieldingly sin-such positions.

A- practical embodiment of this invention is represented in the accompanying drawings, in which o Figure l represents the coal mimngmachine in sideelevation in position-for use, the front portion-of the endless-conveyor being shown therein, Fig.1 is awontinuation of Fig. 1, showing the rear portion of the conveyor and-the 'car torremoving the coal, Fig. 2 is a plan view ot the part-shown in 'FiguL Fig. 2" is aplan view of the part shown in Fig. 1",Fi'g. 3is a detail longitudinal vertical-section through the coal mining machine and the front portion-ofthe-conveyer, Fig.-4. is a detail longitnolinal vertical section through the rear portion' of the conveyer and through the coal-cargFig. -5-is-a transverse vertical section taken- ;in' the plane of the line that ot Filg. 3, looking'i n the direction (it the-arrows, Fig. I 6 is adetail tionthroughthe samevin the plan of'the IineIB of:Fig.' 7 looking in'the direction of thearro-Ws, Fig. 9 is a detail longitudinal vertlcal sectionzon an enlarged scaleof the .front end of. the c0nveyer,'F-ig. i0 is a transverse section taken in the plane of the line C'-C-of Fig."9, looking inthe iiirection of the'arrowsgFig. 11 is an en1arged transverse vertical section taken in the plane ofthe line DAD of'iFig. 1,'- looking in the direction of the arrowaFignlQ is a'eletail horizontal section taken in'the plane ot the line EE of Fig. 11, looking in the direction of the arrows, illustrating the yielding worm gear mechanism for swinging the puncher hori- 'zontally, Fig. 13- isa detail View showing the yieldingworm gear mechanism for swinging the puns-her vertically, and Fig. 14 is a detail section taken inthe lane of the line F-F of Fig. I3,-looking ln-thedirection of the arrows.

The tra'ck tor thecoal rniningmachine is formed in shortsectionscomprising the bottom plate *1 of: sheet'metaL-and the usual track railsQ, 2. 'These'traek sectionsmay be connected by tie plates 3 and bolts tengaging-the abutting ends of the track rails 2, 2, ior forming a continuous track.

between the worm 34 and the t the usual manner by compressed air or steam fed to thecylinder 23 from the main motive fluid supply pipe 21 through the branch pipe 25 r The coal puncher may be swung laterally ,into different desired angular positions and .held yieldingly in such positions by the following mechanism -A worm gear 26 of ring form is frictionally held between the cylinder support 27 and aring 28, in the present instance by providing a plurality of olts 29 projecting from the rin 28 through the base of the-support 27 an interposing springs 30 between the base of the said support 27 and the heads 31 of the said bolts 29. v A ring 32 is secured to the body or platform 5 by screw bolts 33, the inner edge of which ring overlaps the base of the support 27 for retaining the support in 'its position.

A worm 34 is slidably mounted on a horizontal shaft 35 and meshes with the worm gear 26. This wormis yieldingly held in its normal position bysprings 36, 37 interposed hrust bearings 38, 39. The worm 34, shaft 35', springs 36, 37, and thrust bearings 38,39, are housed within a recess 40 in the platform 5 of the machine. The shaft 35 1s driven from a suitable motor 41 mounted on the platform 5, through the following connections :The' shaft of the motor 41 is provided with a pinion 42, whichmeshes with a gear 43 on a stud shaft 44 mounted on theplatform 5.

This shaft 44 has a s rocket andchain connection 45 with the 's aft 35. The motor 41 is driven by compressed air or steam fed through the branch pipe 46 from the main motive fluid supply ipe 21.

. The puncher may he swung vertically into any desired angular position. and held yields ingly in such position, by the following mechanism z- A. wormgear 47 ofring form.

is frictionally held between one of the trunnions 48 and an outer ring 49, in the present instance by providin'g'a plurality of bolts 50 projecting from the trunnion 48 through the rin 49 and interposing springs 51 between t e outer face of the rin 49 and the heads 52 of the-said bolts51. he trunnion 48 and the ring 49 with the frictionally clamped worm gear 47 are rotatably mounted in the sidefframe53 of the cylinder sup port 27 and the other trunnion 54 is rotatably mounted in the side frame 55 of the support 27.- A ring 56 is secured by screw trough.

psprocket chains 75 bolts 57 to the'side frame 53 with its inner edge overlapping the ring 49 thus servin as akeeper for retaining the trunnions in t eir position in the side frames'of the support 27. A worm 58 is slidably mounted upon a vertical shaft 59, which worm meshes with the worm car 47. This w0rm58 is yieldinglfy held in its normal position'onthe said sha 59 by springs 60, 61, interposed between the said worm 58 and upper and lower ball thrust bearings 62, 63, respectively. The worm 58, shaft 59, springs 60, 61; and ball thrust bearings 62, 63 are located in a recess 64in the side frame 53. The shaft 59 is rotated by a hand wheel 65'through inter- 1 meshing pinions 66, 67.

Y A conveyer. is provided for conveying thecoal broken down by the pick, which conveyer is supported intermediate its ends upon a frame 68 provided with traction wheels 69, 69, intermediate its ends, which traction wheels are fitted totravel along the track rails, 2,2. The conveyer-trough comprises a horizontal portion 70 arranged -to extend along the track sectionsbetween the track rails 2, 2,- and an upwardly and rearwardly extended portion 71. for permitting a coal car- 72' to be brought into position beneath the rear end of the conveyer for receiving any desired point.

The platform 5 of the mining machine is so arranged that the mining machine may be-moved back and forth over thehorizontal portion of the conveyer and partially over the upwardly and rearwardlyextended portion thereof. 4

the coal therefrom and transporting it to For the purpose ofmoving the conveyer back and forth from the coal face, the front portion of the conveyer maybe ed away from. the track sections'and suspended in such position by. providing chains 73 depending from the front end of the mining machine latform 5, said chains being provided wit hooks for engaging an one of a series-of hole's'74 along the si es of the horizontal portion 70 of v The conveyer proper. comprises side 75, and cross bars '76 connecting the side chains ate-intervals. These side chains'pas's 'over'i'dler sprocket wheels 77, 77 mounted on a cross shaft 78 at the extreme front end of the conveyer trough: These chains. 75, 75,. also pass around .drive sprockets 79, 79,- fixed to a the shaft 80 of the conveyer chain sprockets 79, 79. The motor 81 i operated by motive .the conveyer cross shaft 80 at the rear end of the con" oeaaro fluid from the main motive fluid supply pipe 21 through the branch pipe 86. The conveyer chains 75, 75, and their cross bars 76, travel rearwardly from the front to the rear of the conveyer along the bottom of the conveyer trough and travel forwardly between the bottom of the conveyer trough and a false bottom 87. This arrangement keeps the chains and cross bars out of contact with the track sections. r

A curvedguard 88 is provided for the front end of the conveyer trough to protect the parts immediately back of the guard.

The endless conveyer shown herein has a series of specially formed cross bars for connecting the chains at frequent intervals, each of which cross bars is angular in cross section, in'the present instance square, and is provided at each end with a round pivot extension 89, which passes through the overlapping ends of two adjacent chain links and is held in position by a fastening means exterior .to the links, said fastening means, in the present instance, being a cotter pin 90. The cross bar is held from turning by providing the same with a recess 91 into which a lug 92 on the chain link enters.

From the above description it will be seen that in operation the endless conveyer may be advanced to bring its forward end into close proximity to the coal face. This may be accomplished by attaching the conveyer to the mining machine itself and starting the motor 20 for moving the mining machine and conveyer up into position, the chains 73 being first attached to the front portion of the conveyer trough for lifting the front portion of the conveyer, a short distance from the track sections. The chain 73 may then be disconnected to permit the conveyer torest upon the track sections. The motor 20 may then be operated for moving the mining machine back and forth over the conveyer without disturbing the same.

'Themotor 81 may be used for operating the endless conveyer to bring the coal from the coal face back under the mining machine and from thence upwardly where it will be automatically deposited into the coal car for removal. The motor 41 may be used for swinging the pick back and forth laterally. The vertical movement of the pick may be accomplished by manual control. 'When it is desired to lay a new track section, the conveyer may be again attached to the mining machine and the motor 20 operated to movethe mining machine and conveyer back a sufficient distance to permit the laying of the new track section. By bringing the front end of the endless conveyer close up to the coal face, it will be seen that a great deal of the coal that is broken down by the puncher will fall directly onto the conveyer, thus requiring less manual labor than heretofore for removing the loose coal from the coal face.

It is evident that various changes might be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the construction herein set forth, but

' What I claim is 1. A track, a mining machine including a platform, a puncher mounted thereon, a motor mounted on the platform for moving the mining machine back and forth along the track, an endless conveyer, means for removably attaching the conveyer to the mining machine, a motor mounted onthe endless conveyer for driving it and a common fluid pressure supply pipe carried by the platform for supplying power to the puncher and motors.

2. A track, a mining machine including a platform, a puncher mounted thereon, a motor for driving the mining machine back and forth along the track, a motor for swinging the puncher laterally into difierent positions, an endless conveyer, means for removably attaching the conveyer to the mining machine, a motor mounted on the endless conveyer for driving it and a common fluid pressure supply pipe carried by the platform for supplying power to the puncher and motors.

3. A track, a mining machine including a platform, a puncher mounted thereon, a motor for driving the mining machine back' and forth along the track, a motor for swinging the puncher laterally into different positions, manually operated means for swinging the puncher vertically into different positions, an endless conveyer, means for removably attaching the conveyer to the presence of two witnesses, this 12th day of January 1910.
